A new protection system of linear generators used for converting oceanic wave energy into electricity

摘要

Almost all of the linear generator used for oceanic wave energy conversion need a protection system against the natural disaster. This paper presents a new protection system for those linear generators for safe operation installed in the ocean. The protection system involves a complete standalone unit, a transmitter, and a receiver unit with a controller. The standalone unit placed in the ocean transmits a set of signals to a receiver situated at a suitable place. A display board is connected to the receiver from which the condition of the oceanic wave can be monitored. Another part of this protection system is the decision making unit which is connected to a motor through a driver. The motor is connected to a pulley with a rope which is further connected to the linear generator to be protected by pulling it in downward direction. Thus, the linear generator can be placed at a safe distance so that it can avoid natural adversity which often causes damages. A prototype is designed and fabricated which is also tested in a water reservoir. The experimental results exhibit excellent features of the proposed protection system.
